LLVMFlang: Fix post-preprocess compile for fixed-form Fortran
LLVM Flang's preprocessor output is always valid fixed form Fortran with
a fixed line length of 72. If an application tries to use fixed form
with a different line length, this will fail in the
post-preprocessing compilation step as they will pass a flag asking for
a different fixed line length.
To fix this we can pass -ffixed-line-length-72 to the post-preprocess
compilation stage. This will be ignored when the input is free form
Fortran, and force to a 72 line length when the input is fixed.
